BACKGROUND: Complications associated with a failed Keller procedure or joint replacement include bone loss and shortening of the first ray. We treated failed Keller resection arthroplasty and joint replacement arthroplasty cases with metatarsophalangeal joint arthrodesis, using an interpositional tricortical autograft from the iliac crest and a low-profile titanium plate. METHODS: This was a retrospective case note review of the patients treated by four consultant surgeons in a university teaching hospital. A Keller procedure was considered to have failed when patients presented with a short, painful great toe with valgus cock-up deformity. Prosthetic joint replacements were considered to have failed based on the clinico-radiological loosening with associated pain. Metatarsophalangeal joint arthrodesis was carried out using an interpositional tricortical bone autograft and a titanium plate. Patients were assessed for resolution of pain, clinical and radiological evidence of fusion and complications. Ten operated feet in nine female patients, with a mean age of 55.9 (range, 37.8 to 80.2) years were followed for a mean of 12.6 (range, 6 to 26) months. Six patients presented with failed prosthetic joint replacements and four with failed Keller arthroplasty. RESULTS: Full clinicoradiological union was achieved in nine of the ten patients as judged by an independent consultant musculo-skeletal radiologist. Four patients needed removal of implants, one for infection, two for prominent hardware and one for implant failure. Eight of the ten patients were satisfied with the relief of pain. CONCLUSION: Failed arthroplasty or Keller procedure is a difficult problem to manage. We recommend complex primary arthrodesis with an interpositional iliac crest autograft and a low profile plate as a salvage procedure.
